It is interesting that Amp Radio never gave up the WODS call letters, unlike other CBS Top 40 Amp stations which sought new call signs. Once upon a time, those call letters indicated Oldies. Of course, if the station ever did return to Classic Hits, no one would call them Oldies.
I can understand the speculation. For the first time in who knows how long, WROR is #1. And not only is Kiss missing from the #1 slot, it's all the way down to #4! The whole rationale for WODS to move from Classic Hits/Oldies to Top 40 was because Kiss was so strong and most large markets have two Top 40 stations.
Of course, I never viewed WODS and WROR as direct competitors. WROR sort of has one foot in Classic Hits/Oldies and one foot in Classic Rock. WROR never (or almost never) plays Michael Jackson, Madonna, Whitney Houston, Gloria Estefan or any rhythmic artist commonly heard on today's Classic Hits/Oldies stations, including WODS before the switch. WROR avoids jingles and, while not as hard-edged as WZLX, probably shares more of its playlist with Classic Rock than most stations that call themselves Classic Hits. On the other hand, very few markets have more than one Classic Hits station, even if one leans Classic Rock and one leans more pop.
So my guess is, CBS will stick it out with Top 40 on WODS.
